Cosmos returns in fine form in its penultimate episode. Sagan explores the historical and scientific precedents for the search for extraterrestrial life (SETI) and our human desires to not be alone in the universe.

2013 is drawing to a close, providing a nice opportunity to reflect on the outgoing year and look back at some of the highlights that we have experienced. Here are my top-20 OSIRIS-REx moments of this past year.

Juno's Earth flyby represented the first opportunity for many of the science instruments to be used on a planetary target. There were terrific photos of Earth and the Moon, plus a cool project to see if Juno could detect intelligent life on Earth.

I once argued that the concept of a space race represented old thinking. The modern way forward in space would be through international cooperation and coordination. Today, I think my insistence that the space race was over was naive. There are now many space races.

Bright and early this morning, we NASA Social folks met at the Kennedy Space Center Visitors Complex for a tour of the space shuttle Atlantis. This is the first shuttle I've seen in person, and it was a stunning sight to see.

I am at the MAVEN launch at Kennedy Space Center for a "NASA Social" event. These events are geared towards space enthusiasts of all backgrounds who are active on social media to increase public awareness and excitement about NASA.

Adolf Schaller, an artist on the original Cosmos series, shares his experience of creating the painting, "Hunters, Floaters, and Sinkers" from Episode 2, which speculates about the possible life living in the turbulent atmosphere of a gas-giant planet.

Today I received my furlough notice from NASA.
